To all whom 'it may concern:

Be it known that I, FRED P. STEVENS, aV

'citizen ofutliellnited States, residing "at Denver, in -tlie county-of Denver and' State of Colorado, have inventeda new and useful F luidfC/ontrolling Means,,of which the following is a specification. j

This invention relates to'means for controlling the passagewayot' fluid from orto a container of any character, and'is clearly capable of use with luids of a gaseous or liquid nature, as will beevident whentlie nature of the inventiony is understood. 4

The principal object of the-.present inventionY is to provide novel and simple controlling-means, bywhicli the amount of Huid.

passing the saine can be quickly and accurately regulated to any amount desired,

or can be cut otl' entirely, means being ein mitted thereby.

A curved passageway 4is cut through the.

A nipple 36a, carried by the casing'secvchamber 24.

`Tlie 'operation of the structure is substantriallyl as 'follows :-A supply conduit can be connected to either the nipple 21 or the nipple 36, and in like manner, an exhaust .conduit-is connected to the other nip le, These conduits lead from or to any siiit ble con-4 tainer, holder or mechanism. 'It wi l theretor-e be evident that' if the pointer handle 33 is'rotated, the valve 25 will be revolved, and different portions of the channel orpassageway 27 will be carried into coacting relation with different portions .of the eccentric passageway4 23. inasmuch as the didcrent portions ofthe passageway 27 are of dil'ere'nt cross' sectional areas, the amount of fluid, whether liquid, 'gas-or `air, will bevaried accordingly', or by turning the valvemember so isl that the channel 27 isentirely out 4ofcoaction with the" channel 23, the passage of Huidl through the casing will be prohibited.- Consequently as the pointer .will indicate on 'the scale the amount of fluid allowed to pass, it will be evident that'the amount can' be accurately andy quickly determined. A different form of constructionis illusj'trated in-Figsj7-10inclusive. In this em bodiment, a "casing 37 'is' "employed having a single chamber 38 therein, with which communicates the bore 39y of the nipple 40'. The upper wall 41015 the'casing constitutes al valve seat member,and projecting therefrom is a .central stem .42. A radial outwardly ltapered passageway43his formed in the inemberl 41 atY one side .of the stem. The Ivalve .member consists of afnam-shaped device 44 "having a sleeve 45 journaled on the stem 42.

Thismember 44 has notch 46 that is movable into alinement with the inner.end of the passageway 43, and the enlarged portionu of lsaid cam in rear of thelnotch 4is arranged to. cover the" passageway 43 either. partiallyor wholly upon'the rotation ot the member, aswill 'be evident. A combined pointer'and handle armv 47, secured to the louterl 'endot' thel sleeve 45, has an actuating knob 48 contiguous to its outer end, and said outer end is pointed, as shown at 49. to cooperate with the scale of a suitable dial 'lhe valve member is heldin coaction with the seat member by a spring disk 51 that bears against 'the outer end ot the stem or. handlemember, and is urged-into coacting relation'therewith by a nut 52 threaded upon exhausted intov the open air. lIt will be eviv.dent, however, that features ofthe invention:

are clearly present in this structure, land that ,the operation otthev parts corresponds to- 'that of` the frstdescribed construction.

l2, a sectional casing 53 is employed, and-between the sections thereof is clamped a valve seat member 54. U From this valve seat member rises "a stem 'that extends -throughthe casing andthrough a stuffing box 56 mounted f thereon.v rlhe valve seat member 54,-",as shown in Fig. 12 is` provided with a passage-y j x 'In the structure disclosed in Figs- 1l and Si;

Way 57 therethrough and a channel 58 that Y extends from -said passageway eccentrically ltothe stem 55,.said channel tapering from the passageway to its outer end-and extending but partially. through thev valve 'seat' member 54. A rotatable valve member 59 has a sleeve 60 journaled on the'stem 55, and said valve member is provided with a radially disposed channel or passageway 61 that .is also tapered. Inlet. nipples 62 coinmunicate with a chamber 63 formed in orf below the underside of the valve seat membei` 54, while another nipple 64 communi- Cates-with the chamber 65in which the valve member is located. A dialplate. 66 is mounted 7on the stutling box, and a combined handle and pointer'67, connected to the 'sleeve 60, constitutes operatin means for the .valve seat member and an inf. icator showing the position thereof. The operation of the structure will be obvious.` There is decided advantage for extendingthe channels but partially throughthe members in that the flow of the fiuid'through the valve can be easily made to correspond to the indicating marks Von the dial.- For instance in making tests, the passageway can be readily enlarged wherever it is found necessary, or if it needs reducing in its cross sectional area at one or morey points, the member can be faced ott over its entire sui-tace until no portion permits more flow than is indicated on the dial by the pointer and those portions which give less amounts of flow can be in creased as desired.

In Fig. 13 another modification of the invention is disclosed. ln this case,-'a casino' 68 is employed, having a nipple 69 connected to one side and having a passageway' 70 extending through its other side, 'this passageway being providedA with 'an outwardly tapered channel 71 formed in the outer face fof-the casing wall. A'stem 72 projects from said casing Wall, and journaled thereon is asleeve 73carrying a cam 74 similar in all respects to thecam 44 shown in the structure disclosed i'n Figs. 710 inclusive. A dial is also in communication with a channel 80 .formed 1n the'opposite side of the plate from which the nipple 7S, projects.

- cease;

o 1s locatedover the casing, and a combinedv handle arm and pointer 76, secured to the sleeve 73, constitutes means for actuating` the` cam or valve seatmember, and also acts The l plate has' a stem 81 -on which is journaled a sleeve 82 carrying a camk v83a that operates over the passagewayv 79.'l ,A suitable dial plate '83; Iis associated'f with ythe structure above described, anda combined handle and .-pointerSt, secured tothe sleeve 82, carrying the. cam, operatesover thedialplate. It

will be` observed that thestructures disclosed ber :inone thatgislL-,not .in the other. `This ,.25

in Figs. v13 andgl/l closely approximate each other, the only di-fferencebeing the air chamvemphasizes the llakit.'ffthatvl.the conduit can be varied as desired.

In the structures disclosed in Figs. 1-I14 inclusive, it willtbenoted that the channels extend only' partially" through the -members containing them. Thiscarrangement is advantageous franumberof reasons. v,In the first place, 'the channels are,las "a"matter ofl is `par. ticularly intended for use in connection witlr'jy apparatus in which a'high degree of accu! fact, very small, for the mechan'l hracy-i's necessary. .-It" wouldltherefore be very `expensive to lform "narrow laccurately tapered channels completely through the members. Furthermore the member would be greatly weakened if the 'support' for the valve had a slitin. it for *a rcomparatively great distance about the post. In addition to the above and perhaps most important is the fact that the maximum amount of air or fluid allowed to flowuthrough the member is determined vbythe size of the small orifice .through said member'and notv by the complete length of the channel.;2 l

From thel foregoing, `it isy hought'thatthe construction, operation, vand many advantages of the hereindescribed invention will be apparent tothose skilled in the art, without -further description, and. it will be understood that various changes in the size, shape, proportion, and minor details of construction,ma be resorted towithout departing from the spirit or. sacrificing any ofthe advantages of theinvention. i
